Abstract—Reactive Powder Concrete (RPC), which can be classified under Ultra High Performance Concrete (UHPCs) vows to be a promising material with respect to its mechanical properties. Its performance under adverse environmental conditions is equally important, especially in marine environment, nuclear waste storage units and chemical industries. Its dense and uniform microstructure may lead to high performance characteristics. Assessing the permeability of a concrete with dense microstructure becomes important with focus on its performance. In view of this, RPC with a compressive strength of 180 MPa was produced using local available materials. Laboratory investigations like; Rapid Chloride Penetration Test (RCPT), accelerated corrosion test and acid tests were conducted to evaluate durability characteristics of RPC. The study reveals that, corrosion rate, chloride ion penetration and loss in mass and strength due to acidic environment is lower than that of high performance concrete, hence, RPC can be a promising construction material to use in aggressive environment.
